How has the Louisiana Scholarship Program Affected students? A Comprehensive Summary of Effects After Three Years
School choice reforms comprise a broad category of policies aimed at improving public education through the introduction of market forces that expand customer choice and competition between schools. Here we summarize our research to date on the effects of a large statewide school voucher initiative, the Louisiana Scholarship Program (LSP), and draw the following conclusions: • Overall, participating in the LSP had no statistically significant impact on student English Language Arts (ELA) or math scores after using an LSP scholarship for three years. • The subgroup of students who were lower achieving before applying to the program did show significant gains in ELA after three years of scholarship usage. Students applying to lower grades demonstrated significant losses in math. • Students without disabilities were less likely to be identified to receive special education services if they participated in the LSP than if they did not. Students with disabilities were more likely to be de-identified as requiring special education services if they participated in the private school choice program. • The private schools that chose to participate in the LSP were disproportionately Catholic, had low tuitions, had low enrollments, and served a high percentage of minority students. We discuss these findings in the remainder of this brief and in greater detail in the three accompanying technical reports. Combined with prior evidence, these results are informative about the specific design of voucher and other choice policies and about how the effects of choice evolve over time as programs mature

Space station attitude disturbance arising from internal motions
A source of space station attitude disturbances is identified. The attitude disturbance is driven by internal space station motions and is a direct result of conservation of angular momentum. Three examples are used to illustrate the effect: a planar three link system, a rigid carrier body with two moveable masses, and a nonplanar five link system. Simulation results are given to show the magnitude of the attitude change in each example. Factors which accentuate or attenuate this disturbance effect are discussed
Global Trade Models and Economic Policy Analyses: Relevance, Risks and Repercussions for Africa
Computable general equilibrium (CGE) models are widely used for trade policy analyses and recommendations. Simulation results from these models have also been used as a basis for offering advice to African countries on what positions to take in multilateral trade negotiations. There is however increasing discomfort with the use of these models for policy recommendations, especially in Africa. In this paper we compare the results of several CGE studies that examined the impact of potential Doha Round reforms on Africa and demonstrate that the results differ drastically both in terms of magnitude and direction. Part of the discrepancies in results can be explained by differences in database, model structure, and choice of parameters. Others are, however, difficult to explain because several studies either do not report key assumptions made or do not provide a clear description of how their framework differs from those in the literature. We also show that the modelling approach and the database used in most CGE studies do not take account of key features of African economies that have serious implications for the impact of trade reforms on Africa. Finally, we outline potential consequences of the misuse of CGE models for policy evaluation and suggest pitfalls to avoid if CGE model results are to be taken seriously by policy makers in Africa.Trade Reforms; CGE Models; Doha Round; Africa
Financing Development in Africa: Trends, Issues and Challenges
Access to finance is critical to successful development in Africa. This paper presents recent trends in various aspects of development finance and provides a critical assessment of the costs of meeting the Millennium Development Goals in the region. It also examines recent proposals for financing the MDGs. Furthermore, it examines the key international commitments made to Africa as well as the extent to which donors have fulfilled these commitments. Finally, it examines issues and challenges arising from recent initiatives on aid and debt.Development; Finance; MDGs; Africa; Trends
The Impact of the Louisiana Scholarship Program on Racial Segregation in Louisiana Schools
The question of how school choice programs affect the racial stratification of schools is highly salient in the field of education policy. We use a student-level panel data set to analyze the impacts of the Louisiana Scholarship Program (LSP) on racial segregation in public and private schools. This targeted school voucher program provides funding for low-income, mostly minority students in the lowest-graded public schools to enroll in participating private schools. Our analysis indicates that the vast majority (82%) of LSP transfers have reduced racial segregation in the voucher students’ former public schools. LSP transfers have marginally increased segregation in the participating private schools, however, where just 45% of transfers reduce racial segregation. In those school districts under federal desegregation orders, voucher transfers result in a large reduction in traditional public schools’ racial segregation levels and have no discernible impact on private schools. The results of this analysis provide reliable empirical evidence that parental choice actually has aided desegregation efforts in Louisiana
